1.21.0 Apple TV/Windows Crash on M3U file/disc control not working

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

This worked yesterday on 1.2.0 (I think that was the version number)

Today the version is updated and I cannot play m3u games on BlueMSX anymore. When selecting an M3U file and select the core, Retroarch crashes.

When selected an individual DSK files and then try to change to a different DSK file, Retroarch crashes as well.

Going back to Factory settings did not solve it.
All other games work. Roms and individual DSK files.

Here is the M3U file:
Super Deform Snatcher - (Konami)(1990)(Eng_Melancholia) (Disk 1 of 3).dsk
Super Deform Snatcher - (Konami)(1990)(Eng_Melancholia) (Disk 2 of 3).dsk
Super Deform Snatcher - (Konami)(1990)(Eng_Melancholia) (Disk 3 of 3).dsk
Super Deform Snatcher - (Konami)(1990)(Eng_Melancholia) (Save Disk).dsk

No source file or test is named. Start by reproducing the M3U launch and the Fast Menu > Disc Control eject/load sequence with the BlueMSX core, then use the supplied log and crash behavior to locate the failing frontend/core path. Done means M3U games launch and disc changes no longer crash on the reported platforms.
